I've Gone and Done Something Mental

I will be interested in how you get on with a direct drive extruder upgrade.

I had under ectrusion problems. I have a 3kg roll of pla which was too big for the extruder to pull. I printed some spool holder with roller bearings which helped massively.
I also swapped the extruder for a dual drive which can be found for 13 quid on amazon.
Also you should do the esteps calibration. If you change your extruder its a must.

BMG is a stand alone extruder. Quiet dear.
You can get brackets that move the standard ender 3 extruder to above the print head. You could print one if you dont intend on using it to print exotic materials.

I took the easy option for direct drive conversion, and bought a complete MicroSwiss direct drive and all metal hot end kit.
It's just under £100 from UK resellers to save anybody searching.
Not a cheap option, but it just works, and I'll be buying another one once I get my new printer sorted out.

There are other cheaper options, but there are rarely any clear cut directions on what exactly is needed for any specific printer.

Is what I have ordered not the correct part then?

 

[ChrisBailey]

I dont think that part will fit the standard extruder, might be wrong though.
Since you are already printing ABS, I would consider a new print head that is all metal and direct drive.
As mentioned above, micro swiss is an option and designed for ender 3.
Titan aero is another although might be more involved to install.

Direct drive is ideal for flexible filaments. All metal hot end would let you print higher temps that 245.

The bowden setup works well though. Check your extuder isnt broken, its common with the plastic extruders. Then check your esteps, its simple and would be the first place to go with extrusion problems.

The extruder in your link looks like a BMG clone.

I bought a direct drive extruder kit, or so I thought. It turned out to be the bracket and cable and it wasn't until I started putting it in that I realised the filament misalignment that it now had. It does say that it is only compatible with the BMG extruder but doesn't actually say what that is. I was under the impression that it was the standard fit. It isn't!

There are no clues about what to buy so looking at the pictures, I have ordered something that looks identical although not called a BMG extruder.

This is the bracket.

This the extruder I have ordered…

You need to visit that Facebook group I posted. They will know all about that stuff...

If it is a plastic extruder.then bin it. Never seen one last long.

No.2 daughter decided she wanted a bit of a Goth themed bedroom makeover, all black and grey walls!

SWMBO went to IKEA and bought a couple of these "boxes". This despite my protestations that I could make them. Apparently I'd "take too long"...

I'd thought I'd have a crack anyway at making some same size, similar ones...just to show her!

Plan is 8 of these 3D printed corner "guides" to hold it all square whilst it glues. Fits 18mm MDF a treat. Will probably use Gorilla expanding glue, no screws.

Using my old EITB design V blocks made when I was an apprentice to support my IKEA copy boxes so I could run PVA down the internal joint. Tbh, the V blocks aren't really big enough, so I got to thinking...

Off I went to the loft and dug out the college books from 40 years ago.

Going to give to No.1 son to draw up in Fusion. Can then scale them up or down!

He can make a centre finder for me too as I've lost the real, steel one! It'll be quite accurate enough for what I do!

Managed to draw in fusion 360 and print for a girl at work

Its to hold a sign made from acrylic

Not that complicated to draw, but a world away from where i was last week

It gets addictive, before long "I can print that" becomes a common phrase.

I like the idea of printing jigs and tool aids.
I have a diy wardobe project on over Christmas so will probly nick that idea. Tbf they look nice enough to use ad edging, just glue them on.

Good for you! I am as impressed as you are.

My most recent prints has been 15 fake etch a sketches for a performance of Elf, they looked in to the real thing but at £20 each it was decided it was unviable. I had to print them at 75% of the real thing though. It has the writing on it I just need to print the knobs next

No.1 has drawn up the centre finder. Just about to print it. This is for my chippy mate who's name is John.

The V block too.

I can post up the .STL files if anyone wants them.

Hello, how does the centre finder work?

It finds the centre

You push the two lugs against the perimeter of say the "soup tin". Draw or scribe a line along the straight edge. Move the finder around, keeping the lugs against the perimeter and draw another line. Where the two (or more) lines bisect is your centre.

Once printed I'll take pics of how it works.

I’ve got a metal one that does the same thing. It was my grandads
